This invention relates to improvements in boot and shoe sock liningsdevised with the objects of giving, as compared with socks hithertodevised, better resistance to Wear,

5 freedom from rucking, ease when putting on the boot or shoe, comfortin use, protection from dampness, and hygienic properties.

The invention is illustrated in the accompanying drawing in which Figure1 is aperspective View of the sock lining and Figure 2 is a fragmentarysectional view thereof on an enlarged scale.

The essential characteristic of the improved sock lining according tothe invention is that it is composed of'board-like material to whoseupper surface is imparted a rubbed permanent gloss. rIhe board is made,for example, by the same process as ordinary mill board, the ingredientsbeing vegetable fibres which are disintegrated in pulpers and beaters,and the pulp converted into sheets by the ordinary drum mould papermaking machine. The rubbed gloss on the upper surface of the board isproduced (see my divisional application Ser. No. 427,939, tiled February12, 1930) by passing the sheet under a ball of very hard metal, such aschilled cast iron Which is carried by the end of a heavy suspended beam,the sheet being placed between this ball and a bedplate which theoperator presses up to the ball with' a foot pedal. The beam worksbackwards and forwards relatively to the operator who manipulates theboard so that it is traversed along diagonal lines at a very acute angleby the ball. The ball gives a stroke about an inch wide and creates byfriction a permanent and veryhigh rubbed gloss.

The rubbed gloss so produced on the board has very advantageousproperties in a sock 40 lining because it allows the foot to slip easilyover the surface of the sock lining when putting on the boot or shoe,which opera-tion is thereby greatly facilitated. Moreover, the

smoothy running prevents the sock lining from being rucked or torn bythe rubbing of the foot. An adhesive gloss Would not be suitable for thepurpose lowing to the heatof the foot. ,1

The under surfa e of the sock lining is preferably coated or impregnatedwith a,

Waterproofing medium such for example as paraffin wax. "Ihe latter maybe applied simultaneously to two sheets of the glazed board by holdingthe two sheets together with their rubbed surfaces in contact and thenpassing both together through rollers which distribute the Waterproofingmedium on the outer unrubb'ed surfaces of the sheets. Thel sheets arethen complete and ready for the different sized knives to stamp out theseparate sizes, pairs of knives being provided, i. e., a right and aleft for each size.

'Io impart hygienic (antiseptic and prophylactic) properties to the socklining,

`chemical substances are incorporated in theA course of its manufacture(see my divisional application, Ser. No. 427,939, filed February 12,1930), either by mixing in the pulp or by impregnation of the sheet orby both. As chemical substances, boric acid` formaldehyde and salicylicacid may in particular be used. Others which may be used are alum,sodium. benzoate and boraX. For example, the treatnient with chemicalsmay be effected by mixing the pulp with a 1% solution of alum and byimmersing the sheet, after pressing, in a solution containing salicylicacid 0.1 parts by weight, sodium benzoate 2.5 parts, boric acid 2.5parts, borax 2 parts, formaldehyde 0.2 parts, and water to produce 100parts by volume.

What I claimis 1. A boot and shoe sock lining composed of board-likematerial whose upper surface has a permanent rubbed gloss.

2. A boot and shoe sock lining composed of board-like material whoseupper surface has .a permanent rubbed gloss and Whose under surface istreated with a waterproofing medium.

y, 3. A boot and shoe sock lining composed of board-like material Whoseupper surface has, a permanent rubbed gloss and whose under surface istreated With paraiiin Wax.

In testimony that I claim the foregoing as my invention, I have signedmy name, this 3rd day of May, 1929.
